This is a typical installation of the dual stage air-assist in the Nova series machines. Your configuration may differ slightly.
The maximum recommended operating system pressure, according to Thunder China Engineering, is now 40 psi to help prevent premature air solenoid failures.
This is the back side of the main air inlet on the rear of the laser. Line #1 is supplied from the compressor at the inlet and travels to the solenoid bank.
At the solenoid bank, #1 splits and goes into the inlets of the 2 identical air solenoids (these are normally closed valves). These solenoids control the raw air inlet to the stages. Line #2 is the low volume stage and line #3 is the high volume stage.
Then lines #2 and #3 go to their respective needle valves. the 2 stages exit the valves and combine back into one line, line #4.
